l Specieation of Letters Patent.

Patented Nov. 17, 1914.-

Applieation filed September 25, 1918. Serial No. 791,822.

To all whom it may concern Be it known that I, CHRISTOPHER C. BoviuN, a citizen of the United States, residing at Norfolk, inthe county of Norfolk and State of Virginia, have invented new and useful Improvements in Window-Screens, of which the following is a specification.

This invention relates to improvements in window screens, and it has for its objects primarily to provide a screen which can be placed onthe outside of the window in such manner as to avoid interference with the raising and lowering of the lower window sash and will avoid interference with the fastenings of outside blinds or shutters when such are used, enabling the blinds or shutters to be opened and closed conveniently, which can be readily accommodated to window openings of different widths and heights and will maintain a tight'closure to exclude flies and other insects, and `Vwhich can be manufactured and installed; readily and cheaply. c

To these and other ends, the invention consists in certain improvements, and cbmbinationsY and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

ln the accompanying drawing: Figure 1 is a perspective view of a window showing a screen constructed in accordance with the present invention applied thereto; Fig. 2

. represents a `vertical section through the guides; in proper'position. f Similar parts .are designated window showing the position of the screen with` respect thereto; lF ig. 3 represents a horizontal section on the lineS-B of Fig. 2; Figs. 4 and 5 are detail perspective views showing the construction of the upperiand lower railsofthe screen; Fig. 6 is a detail the upper portion of the screen to p rovide aniexit for flies; Fig; is a .detail view of the catches,- whichhold the Vlower ends of the by the same reference characters in the several views.

Window Ascreens. embodying the present .in-

.ventionlare ap licable generally to'windows of di'ferent sty es, the screen in the present instance being shown .in connection with. a window .of the usual construction.' It will f be understood, Vhowever, that the invention 'I of which willlbe .inclu is not restricted in this regard' and also that modifications and changes may be made, all

ed within the scope of the claims at the end of this specification.

In the )resence instance, l designates the window rame having a sill 2, and 3 designates the upper sash which is showmin its usual elevated position and is fitted in .the grooves or channels 4 formed in the opposite sides of the Window frame. The screen cmbodies a section of screenY cloth 5 which is preferably metallic or composed of Woven wire and corresponds substantially in dimensions to the size of the opening defined by the `sides of the window frame, the sill, and the lower rail of the upper sash. The lower edge of the screen cloth is attached to the lower rail 6 of the screen, which may be of wood, by a strip 7, the latter being composed preferably of sheet metal havin the lower edge of the screen cloth secure thereto by folding the strip, the strip being secured by screws or other suitable means to the lower rail 6 of the screen. The upper edge of the screen cloth is secured to the `at the bottom, and the upper edge of the screen cloth is folded or doubled so as to fit into this groove in the upper rail, it being secured therein by a bar 9which is inserted into the folded portion of thescreen cloth and introduced into the groove in the rail 8; One edge ofthe upper rail is preferably folded and turned outwardly to form a stiifening flange 10 and the retaining bar 9 is preferably locked or held in position relatively to the upper rail 8 by a pair of tongues 11 which are formed byjsplitting the ends of this bar and folding such ton ues against the rail 8 so as to lie above the shown in Fig. 4.

A pair of guides are provided at the opl u posite sides of the window frame to l'coperate with the screen to guide the same and to also produce tight closures at these' points to eifectuallyexclude iies and other insects.'

In the present instance, a pair of such des 12 aresho'wn, vthese 'des bein simi ar in construction and being of ange form in cross section, the guides being fitted into the sash grooves or channels 4 with the outer flanges 13` lying. against. the bottoms of, the grooves and the other flanges 14; of the of the guides -arefretainedwin catches l5, each'having upstan ing anges sition by fitting them between the lower corners of the upper sash and the respectivev walls of the groove while the lower ends o sition by formed with slots 16 to receive the inturned anges 14 of the respective guides. The

'inwardly toward outsid blinds or shutters, but alsoinsures Contact between the guides and the side edges of the screen cloth throughout the height? of the screen, it' being understood that these'sideedges of the screen are 11nattached or not provided with raiis. In order to insure 'such contact between the side edges of the screen` and the guides, means is provided for maintaining "the screen under tension.

According to the presdntinvention, a pair oftension springs y V18 are provided, thesesprings being at# tached to the upper part. of the window,

frame by the eyes 19 and are fastened at their lower .ends lto the upper reii ci the .screen, these springs exerting a constant wie.

tensionfupon the screen and4 hencel causing they side edges thereof to lie in 'close contact with the vntilrned v"iin'nges 14 ofl ythe 1 guides, thecurved or'con'vexed forni of the; guides insuring contact between them and the screen cloth throughout their e tent.' "A

suitable catch is also rovided to ormalljy' retain .the 'screen' in Ac osedposition' in op;v position' td-thezlifting action of the springs. 18.. 'The catch shown 1n the.- present'. iii-' stance embodies' an' e e or ,staple 20 .which is securedt the win -o w lsill anda 'pro'ection 2 1'wliich is-securedto the lower rail 6 of` thegscreen.

'The lo'iiiner railHL- ciy the screen "is also heldin proper`pos1tionbyltheguides' 12.'. 'In the constructioniis'hown, means. is provided for` raii 6 ofthe screen to have a limited nimeer accommodate the width of the screen to the width of the window opening, andthe upperrail 'of thescreen can bereadily cut to the proper length. rlhe height of the screen can be adjusted readily bymaking a fold 70 of the proper length in the screenv cloth at the point where the latter is secured tothe upper lrail.-` Theopening provided between each slide 22 and the .strip 7 for the guides l2 is suiciently large Lto permit the lowr 75 roc ing movement, this rocking movementI of the lower rail of the screen serving to en` gage and disengagethe'. catch composed of the eye 20 and the projection 2l. When it g@ is. desired to open or close the outside blinds or shutters, it is only necessary to rock the lower screen rail 6 to disengage the projection thereon from theeye, thesprings 18 then operating to lift the screen a distance 35 suihcient to admit the hand'to. theblind fastenings, the screen, however, being'noi'mally retained in its lower closed-position by the .Y catch as described. ifi desired, a device such as that shown in Figs. 2 and 6 maybe 90, provided for temporarily 'dee'cting the -up-` :per I'end of the screen .outwardlyte "provide an exit'ior iesa' This device es` shown consists of aplate25 which is piwitelib'at'26` Vtethe under side ef the upper sashl 3, Lnis 95 catch, when it occupies 'the position shown in Fig. 2, being disengaged from the screen, j the Iupperrail of he screen then lying directly aga-institli" f outer 'side 'of 'the lower rail' ofthe upper-' s` a`sl1 f3,l asi'shown in Fig. 2', 10o and when turned 'into thepositin shownin f 6,' it willv 'engage' and force outwardly .the upper'endof the screen, providing an exit between the *flipper end of the screen andthe lower rail v"of the'upper sash. 105
